About Wild Yaks
Wild yaks usually are found in herds of ten to thirty animals.
They have dense close matted under hair as well as shaggy outer hair.
Wild yaks secrete a special sticky substance in their sweat which helps keep their under-hair matted and acts as extra insulation. This secretion is used in some traditional Nepalese medicine. Many wild yaks are killed by hunters in China and are now a vulnerable species.
